SP are indeed good products at great pricing. Only problem I found, from actual experience, is them honouring the warranty. On pretty much every occasion they have rejected it and told me to go to the point of sale and sort it out with them. Even when it is past a reasonable time frame eg 2 years into the 5 year warranty. Shame as that is the one downside, and major one, on otherwise excellent choice.
